I know exactly what you mean. That is why I would love to do my own resto kind of shop doing EVERYTHING. I went to goodguys show here in NC and every car I saw was really nice and they had a list on the front that says what was done by them and what wasn't... Interior and paint was something that WAS NOT done by them. I didn't see a single one I don't think. I did see that MOST of them there used PPG red paint haha. Around here there is no interior shops either. There are a few about 30 minutes or so but they are like what you said, they will just recover a seat and sew up a tear, etc. Nothing major or custom. When I am done with college I will probably look into something like interior and maybe start something if I am lucky and work my tail off, and I am sure it would be good money since not many people around here doing it. All just a matter of money and actually DOING it to learn.

www.dogpile.com <--- go there and type in Automotive Interior Supplies or such. dogpile.com searches everything together like google, ask geeves, yahoo search, MSN search, etc... It will come up with A TON of things I am sure.
